The indianapolis 500 is one of the most exciting events in sports. each spring, 33 drivers compete in the 500-mile race, sometimes hitting speeds of more than 220 miles an hour. the general formula for computing distance is rate (or speed) multiplied by time, given a steady average speed. the formula may be written d = rt. answer today's project questions on speed, distance, and time.

the driver's average speed to complete all 8 laps is miles per hour. round to the nearest tenth of a mile per hour.

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.
